How to get the internal and external sdcard path in android

Question

Most of the new android devices have an internal sdcard and an external sdcard. I want to make a file explorer app but I can\'t find out how to get the path to use in my app

Answer 1

File main=new File(String.valueOf(Environment.getExternalStorageDirectory().getAbsolutePath()));
File[]t=main.getParentFile().listFiles();

for(File dir:t)
{
    Log.e("Main",dir.getAbsolutePath());
}

Output:

E/Main: /storage/sdcard1
E/Main: /storage/sdcard0

I have one SD card and inbuilt memory.
